摘　　要：建立了杨树菇培养料中5种农药消解动态气相色谱分析方法。样品用乙腈提取,提取液浓缩后用弗罗里硅土柱净化,经石英毛细管柱分离后,采用GC-ECD同时测定六六六(α-BHC、β-BHC、γ-BHC、δ-BHC)、滴滴涕(o,p'-DDT、p,p'-DDT、p,p'-DDD、p,p'-DDE)、毒死蜱、溴氰菊酯、氯氰菊酯5种农药消解动态,5种农药最小检出量为2.8×10-10～1.6×10-8 g,最小检出浓度为0.000 15～0.053 00 mg·kg-1,相关系数≥0.995 4,半衰期分别为33.02、53.14、18.21、18.16、9.40 d。A gas chromatography(GC)method was developed for determination of 5 pesticides degradation dynamic in the sample of Agrocybe aegerita composts.The sample was extracted by acetonitrile and cleaned up by florisil column,separated by quartz capillary column.Degradation dynamics of BHC(α-BHC,β-BHC,γ-BHC,δ-BHC),DDT(o,p' –DDT,p,p' –DDT,p,p'-DDD,p,p'-DDE),Chlorpyrifos,Deltamethrin,Cypermethrin were determined simultaneously by GC-ECD.Minimum detection amount were 2.8×10-10-1.6×10-8 g.Minimum detection concentration were 0.000 15-0.053 00 mg·kg-1,relation coefficient≥0.995 4,Half-life were 33.02 d,53.14 d,18.21 d,18.16 d and 9.4 d,respectively.
